8 Claims. (Cl. 221-28) Our invention relates to metal containers, suchas pails, cans and drums, arranged for containing liquids, and having atthe top or side ,thereof a spout for facilitating pouring of the liquidfrom the container.

An object of the invention is to provide lthe container with anextendible spout which may be projected to a considerable distance fromthe container proper, yet need not be retracted or ll backed into thecontents of the container when not in use.

Another object of the invention is to provide an extendible pouringspout which will permit discharging of the contents from the container,both in the extended and in the retracted positions of the spout, andregardless of the amount of liquid remaining in the container.

A further object of the invention is to provide a spout which may beextended fr'om the container in different curved and angular positions.

A still further object of the invention is to provide a device of thecharacter described, in which all of the parts of the spout and theappurtenances thereof, including a means of insuring the admission ofair to the container during the pouring operation, may be combinedandassembled in the form of a single unit and applied as such to thecontainer Walls.

The invention possesses other objects and features of advantage, some ofwhich, with the foregoing, will be set forth in the followingdescription of the preferred form of the invention which is illustratedin the drawings accompanying and forming part of the specification. Itis to be understood, however, that variations in the showing made by thesaid drawings and description may be adopted within vthe scope of theinvention as 'set forth incthe claims.

Referring to said drawings:

Figure 1 is an enlarged longitudinal sectional view of the spout unit asapplied to a container wall and showing the spout in an extendedposition for normal use.

Figure 2 is a view similar to Figure 1 but show- 45 ing the spoutretracted and covered.

Figure 3 is a side view of a portionv of a container, with parts brokenaway to show the spout unit.

Figure 4 is a plan view of the container and unit as shown in Figure 3.

Figure 5 is a sectional ,view similar to Figure 2, but showing the unitas applied to a diierent form of container head. l

Figure 6 is a bottom view of the unit 55 tached from the container wall.

as de- Figure 7 is a vsectional view of a unit of somewhat modifieddesign.

As illustrated in the drawings, the spout unit 2 is applied to a head 3which forms part of a container 4 and has formed therein a discharge 5opening 6 about which` the unit is disposed. In the embodiment of theinvention illustrated in Figures 1 to Il, the head is formed withadiametrically extending upset portion 'I containing the opening 6 anddefining on the inner side of l0 the head an inverted channel 8 whichgradually decreases in width from a point adjacent one edge of the headand where the opening' 6 is located, to a point at or adjacent theopposite edge of the head. l5

'I'he spout unit, as here shown, is made up with what may be termedinner and outer necks 9 and I0 arranged in concentric relation and inregistration-with the opening 6. The necks are formed with base portionseach designed for iixed connection with the head, and desirably the baseI2 of the inner neck vand the base I3 of the outer neck are arranged tobe secured together and applied to the head as a unit. In the presentform of the invention, a ring I4 is made part of the unit and such ringholds the-base I2 against the base I3 and forms with the latter theiiange of the unit wherewith'the cooperating ange I6 of the head isinterlocked to provide anl effective seamed joint.

The inner neck is arranged to provide anextendible spout and is formedof a plurality of tubular sections I'l of which the base I2 may be'considered one section. The sections are formed progressively one ofsmaller diameter than the other 3 so that one may nest within anotherand each is tapered or otherwise formed so that the sections maybeextended one from the other to an appreciable though limited extent,and when so extended the jointsv between the sections'will besubstantially liquid-tight and the outermost section I1 may be disposedconsiderably outward from the base section I2 and with its outlet ori-`flce well advanced beyond the rim I8'of the container. The sectionsmaybe made progressively smaller in diameter from' the section I2 to thesection Il and thus arranged to surround the section I2 and whenretracted or collapsed to lie in the space between the inner and outernecks 9 and I0, or as here shown, in order to permit greater facility inmanipulation, the diameter of the sections decrease from the section I2to section I1 to lie within the opening defined by the section I2. Inkeeping with the latter arrangement, the ring member I4 has a portion I9 which extends partlyinto the opening 6 and provides a stop or supportfor the sections when the latter are retracted one within the other, orin other words when the spout is in collapsed position. Desirably thering portion I9 is perforated or otherwise formed so that the free flowof the contents through the opening 6 will not be interfered with or thecapacity of such opening restricted.

A full lip is provided along the outer rim of the section I1' so as tofacilitate pouring of liquid from the spout without spilling or runningbackward along the sides of the latter. Preferably the lip 20 is madelarge enough to project over and cover all of the other sections whenthe spout is collapsed as indicated in Figure 2. Furthermore, thesections are preferably so formed and'de- 4 signed, that when inretracted position, the outer end of each of them will lie inwardlyofthe outer end of the outer neck I0, and thus when the sections are sodisposed they will be completely shielded by said neck. A cap, 22, maybe'positioned on and engaged with the end 2l whenl the spout iscollapsed, so as to close the opening 6 and seal the container thereat.

It is important to note that with the device of our invention, noportion is required to protrude into the interior of the container,either in the extended or retracted positions of thespout. In this way,regardless of the amount of liquid in the container or the position inwhich the container is held during the pouring operation, the free flowof the liquid from the container will in no manner be interfered with.Furthermore, regardless of the depth of the container, the spout may beconstructed so as to extend outwardly from the container headpractically any amount desired. It is to be also noted that the portionof the base section I2 between the point of attachment of the head andthe innermost point of engagement of such section and the next sectionwhen the latter is in extended position, is formed in a smooth curvefrom which the wall of said next section may extend in tangentialrelation. It will thus be clear that when the sections are extended asindicated in Figure 1, the liquid from the container may flow smoothlyand easily into and through the spout. Of importance also is the factthat since the lower section I2 is formed as a fixed part of thecontainer and extends outward therefrom to an appreciable degree, thesmooth and free flow of the liquid can under some circumstances bepermitted without extending the sections.

A feature of considerable advantage which arises out of the sectionaldesign and of the manner of connection of the sections, is the exiblenature of the spout when in extended position. By reason of thisconstruction not only may the spout be extended in different angularrelations to the head, but the spout may be extended in a curve so as toposition the spout discharge orifice as defined by the lip 20 inconsiderable angular relation to the orifice 6 and well over the outerneck I0.

Preferably included as a part of the spout unit and arranged forapplication as such to the container head, is a means insuring the flowof air to the interiorfof the container as the liquid is being pouredfrom the spout. As will be clear from Figures 1 and 2, the outer neck I0and the base section I2 of the inner neck are spaced to define anannular chamber 26 which bymeans of an opening 21 at the bottom thereofis afforded communication with the interior of the container. i

In order that the chamber may have communication with the uppermostportion ofthe interior marginal portion 32, and when the spout is put.metrically opposite the opening 6. For the operative connection andattachment of the pipe to the spout unit, the portions of the base I2and the ring I4 at the opening 21 are offset and the ring is formed witha laterally extending socket 29 in which one end of the pipe is rmly butdesirably removably held. It will be understood that during the pouringoperation, the chamber 26 is uncovered, and therefore the air may iiowfreely thereinto and into the pipe during said operation. No restrictionof the discharge opening i is entailed, and when the cap is positionedover the unit as in Figure 2, the opening 21 as well as opening 6, isclosed and sealed. It will be noted that the channel 8 provides ashielded cav- 20 ity for the reception of the air pipe.

In the form of the invention, illustrated in Figure 5, the unitis simplypositioned on the container head with axis of the `discharge opening 6and of the spout unit perpendicular to the plane of the head. Thisarrangement avoids the use of the diametrically extending offset in thehead, and any desired inclination or curvature in the spout for insuringready pouring over the rim of the container is effected by flexing thespout u through appropriate relative positioning of the sections;

In Figure '1, a modified form of closing and sealing means is providedfor the spout unit. As here shown, the upper portion of the outer neckI0 is extended to provide an integral cap or closure 3| which togetherwith such neck forms a complete and sealed enclosure for the inner neckincluding the spout sections. The closure portion 3| is connected to theneck by a weakened into initial use the portion 3| may be -readilysevered from the remainder of the neck so that the spout sections can bewithdrawn and exitended from the enclosing rvck portion I2. Desirablythe cap portion 3I in its position before removal from the neck, liesdepressed below and inwardly of the rim of the latter so that upon thesubsequent removal of the cap portion the rim will remain smooth on theinner side of the neck. A cover 33, designed for threaded engagementwith the neck, is provided for closing and sealing the opening in theneck Awhen the cap portion 3| We claim:
